Question:
I HAVE A 2021 RAM 2500 MEGACAB W/RAMBOX 4X4 DIESEL. WHAT 5TH WHEEL HITCH, ABOVE BED RAIL KIT AND SIDEWINDER PART NUMBERS WILL I NEED TO TOW A GRAND DESIGN REFLECTION 311BHS CAMPER?

Hey Gary! Since you have the RamBox you will need a fixed 5th wheel hitch to tow the Reflection. If you want above bed rails I recommend the B&W Patriot # BW29XR. This includes the rails and everything else you need for installation. If you would rather not have the rails in your truck bed, the B&W Companion # BW53QR is the best option. This comes with their Turnoverball gooseneck hitch, which you will use to mount the Companion.
Unfortunately, the Sidewinder isn't something I can help you with right now. Reese is for sale following the bankruptcy of First Brands and we haven't had those in stock for quite a while. You will have to search around to find one, or perhaps even find one on an old trailer that can transfer to your Grand Design. A rotating pin box is the only option with the RamBox so there really is no other choice.
Where are you headed with the Reflection once you get everything set up?
